This troubleshooting guide is intended to assist you with certain problems which may occur. If you still encounter problems, see your Authorized Rockford Dealer for assistance.

Problem

Amplifier will not play — Remote Turn-on light is off.

Solution

1.Check the DC voltage at the amplifier’s B+ terminal with a voltmeter. The voltage should measure between 11.5V - 15.5V.

If voltage is not found, check the battery, fuse, fuse housing and wire connections. Fix, repair, or replace accordingly.

2.If the amplifier still does not play, check the voltage at the amplifier’s remote turn-on lead. The voltage should measure between 11V - 15V.

a.If voltage is above or below the prescribed measurements, check for proper connections and have the head unit checked by an Authorized Dealer or Service Center.

b.If the remote turn-on current draw from the head unit is connected to multiple amps and/or electronics, the current draw may be too great. Check for proper connections. (Use a relay to suppress the excessive current draw.)

Problem

Amplifier will not play — Remote Turn-on light is on:

Solution

1.Unplug the head unit and test the amplifier with another working source unit (i.e., bench-test radio, walkman, etc.). If the amplifier plays, check the in-dash leads for cuts, breaks and/or shorts.

2.If the amplifier still does not play, disconnect the existing speakers and connect a set of test speakers to the output of the amplifier (any type of speaker will do - i.e., simple home box type, bookshelf, raw speaker, etc.). If the amp plays, check for shorts or blown voice coils in the vehicle’s speaker system.
